Oleodinamica Marchesini V1121/VMP RFP3 1/2 OMP/OMR C/VMP three-way pressure-compensated flow control valve

Oleodinamica Marchesini V1121/VMP is the RFP3 1/2 OMP/OMR C/VMP three-way pressure-compensated flow control valve, with a factory maximum operating pressure of 350 bar and mass of 3.426 kg.

The factory inlet-flow limit is 80 l/min, while the maximum adjusted priority flow is 60 l/min. The pressure compensator maintains the adjusted priority delivery as downstream pressure changes; excess flow is returned to T. The integrated relief limits pressure on the regulated priority circuit. Maximum inlet flow, adjusted flow and component pressure are separate limits.

This version mounts directly on the Danfoss OMP / OMR interface. The exact factory drawing gives body length 100 mm, height 94 mm and thickness 50 mm. The original connection paragraph refers to M1/M2 motor ports, whereas the body drawing uses E/P/T labels. No unqualified external port-to-function map or pipe-thread specification is assigned until that notation is clarified. Use the complete exact interface drawing when checking the motor assembly.

The zinc-plated steel body contains hardened and ground steel parts with standard BUNA-N seals. The original factory hydraulic symbol and exact article drawing are retained in the local PDF. Where the manufacturer describes slight internal leakage, the component is not represented as a zero-leakage shut-off device.

The local technical PDF contains the complete relevant manufacturer spread, including the named article or accessory drawing. Neighbouring valve ratings and optional configurations apply only to the corresponding identified part. Any 50 °C oil temperature and 30 cSt viscosity beside curves are reference conditions.
